Billy, It depends if the engine is 4 or 6 cylinder. Seems with the 2005 Sienna, they do recommend turning the crankshaft counterclockwise by 60 degrees prior to removing the belt to release the spring tension. So my questions is, When I remove the timing belt, can I align the rear camshaft pulley to the notch with a wrench? Hadn't been that far into a car repair before, so I feel pretty good. Pistons are made of high temperature-resistant aluminum alloy. Here is the link: down below is the engine model. Make sure that the deck on all blocks are surfaced. If someone thinks I'm wrong then fine but I just don't see how this info is so special it wouldn't be in that already existing sticky which has taken years to build.
I know my way around a few nuts and bolts, I've done this sort of thing in my younger days, but I'm more of a non greasy, put in nice stereo, tint the windows and make it shine in and out. You can also have a wireless smartphone charger. Could it be coming from the rear cam seal? After the mount has been removed, unbolt the mount bracket which will allow access to the belt tensioner bolts for removal. Bore and stroke is 87. This motor features an aluminum block and was introduced in 1994.
Time Needed Allow three or more hours to replace the belt alone. Reminder: marking the old belt with paint where it meets the crankshaft and camshaft pulleys, and transfering these marks to the new belt, will make it much easier to install the belt if any of the pulleys happen to move between the removal of the old belt and the installation of the new one. This is done to achieve correct piston skirt clearance. The family introduced many changes for Toyota, including various , , and engine improvements from generation to generation. A small amount of slack will now exist between both camshafts and between the right camshaft and the crankshaft.
The disconnection is made by separating two clutches, one in the front axle and the other in the rear, so that the losses and vibrations are minimized by uncoupling the transmission shaft completely.

The exhaust cam is driven by intake camshaft through gear in the middle of the cylinder head. These should always be removed to ensure that the oil galleys are cleaned of any contaminants. The galley can be repaired by sleeving the galley and drilling the oil holes, but the amount of time taken to do that probably is not cost effective. If cylinder head removal is done without motor removal, many times it will be difficult to remove the crossover pipe nuts.
Being off by one cog will cause an engine misfire. The crankshaft is supported by 4 bearings inside the crankcase. It has a forged steel crankshaft and cast. Click on a photo to enlarge it. Doc this is a really great thread with very useful info. The pin can be knocked out on new and remanufactured water pumps that have the pin if it is not needed for the later applications. Gradually loosen the cam cap bolts one to two turns at a time, letting the valve spring pressure remain uniform across the camshaft.
This engine also features an oil cooler and a ignition system with three coils. After 200,000 miles, I would definitely replace the seals camshaft, crankshaft, and oil pump and the water pump as well, along with the timing belt. The toothed timing belt is used to drive the camshaft. Have watched a number of YouTube videos. After installing the belt, you can do a compression leakage test to make sure the valves are still okay. The front fascia refined with funkier headlights and stylish bumper. I remove the belt but messed up the timing marks.
Cleaning includes readout of injector flow before and after cleaning and the percentage of improvement. Earlier heads may be machined to be adapted if necessary. Different applications had a bypass nipple while some did not. Applying alternating equal turns on each bolt will gradually compress the tensioner pin against the tensioner pulley assembly. Shop and compare prices, including shipping costs, for the best deals. As this occurs, the timing belt will tighten up.
The video contains the procedures described in the text below, though it has some of the steps in a different order. The crankshaft is integrated with 9 semi counterweights for balance. Just adds to the confusion of a simple job. The guide pulley can be easily replaced by unbolting the old and bolting on the new. Recheck the 3 timing marks, unfortunately they are not aligned.
